It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0026] Please refer to Figures 1 to 8, an efficient filtering device for a purification workshop provided by an embodiment of the present invention includes a frame 5, a filter net 15, and a fan. The filter net 15 is used for filtering fluff. An input pipe 1, an output pipe 2, and a motor 6 are fixedly installed on the frame 5. Air enters from the input pipe 1 and then exits from the output pipe 2. A rotating ring 3 is rotatably installed between the input pipe 1 and the output pipe 2, and the motor 6 drives the rotation of the rotating ring 3. The inner side surface of the rotating ring 3 is fixedly connected with a filter net 15. The filter net 15 is disc-shaped, and the surface of the filter net 15 is wear-resistant and has a high hardness. First V-shaped plates 12 and second V-shaped plates 13 are respectively arranged inside the input pipe 1 and the output pipe 2. The first V-shaped plate 12 is connected to the inner wall of the input pipe 1 to form a first V-shaped cavity, and the second V-shaped plate 13 is connected to the inner wall of the output pipe 2 to form a second V-shaped cavity. There is a gap between both the first V-shaped plate 12 and the second V-shaped plate 13 and the filter net 15. One ends of the first V-shaped cavity and the second V-shaped cavity far from the filter net 15 are sealed. A blade 14 is installed on one side surface of the first V-shaped plate 12. The blade 14 contacts the surface of the filter net 15. The blade 14 is used to scrape off fluff impurities on the surface of the filter net 15, and the scraped-off fluff impurities will fall into the first V-shaped cavity. A central shaft 16 is fixedly connected to the center of the filter net 15. A rotation-to-reciprocating linear component, a reciprocating seat 20, and a sector plate 21 are installed in the second V-shaped cavity. The central shaft 16 drives the rotation of the rotation-to-reciprocating linear component, and the rotation-to-reciprocating linear component drives the reciprocating linear motion of the reciprocating seat 20. An arc-shaped groove 34 is arranged on the side surface of the reciprocating seat 20 facing the filter net 15. A sliding seat 35 is slidably connected in the arc-shaped groove 34. The sliding seat 35 is connected to one end of the arc-shaped groove 34 through a return spring. A sector plate 21 is fixedly connected to the sliding seat 35. A large number of telescopic hole-clearing rods 36 are installed on the sector plate 21. The telescopic hole-clearing rods 36 are used to clean the mesh holes of the filter net 15. The fan is installed in the output pipe 2. The fan is not located in the second V-shaped cavity. The fan is used to guide air from the input pipe 1 to the output pipe 2. Through the settings of the rotating ring 3, the first V-shaped cavity, and the blade 14, the fluff impurities on the surface of the filter net 15 can be scraped off and the scraped-off fluff impurities can be collected, which is convenient for centralized cleaning. Through the settings of the rotation-to-reciprocating linear component, the reciprocating seat 20, the sector plate 21, and the telescopic hole-clearing rods 36, the mesh holes of the filter net 15 can be cleaned, and the device can be used normally during the cleaning process without interruption.

[0027] In an embodiment of the present invention, both end faces of the rotating ring 3 are rotatably connected to the input pipe 1 and the output pipe 2 respectively. The input pipe 1 and the output pipe 2 are both horizontally arranged. A first gear 7 is connected to the output shaft of the motor 6. A toothed ring 4 is coaxially and fixedly connected to the outer side surface of the rotating ring 3. The first gear 7 is meshed with the toothed ring 4.

[0028] In an embodiment of the present invention, a plurality of sector-shaped filter plates 8 are further installed in the output pipe 2. The sector-shaped filter plates 8 are HEPA filter plates, which makes the air purification effect better. The size of each sector-shaped filter plate 8 is smaller than the cross-section of the second V-shaped cavity. The plurality of sector-shaped filter plates 8 are in contact with each other to form a circular shape with a notch, and the notch is located in the second V-shaped cavity. A convex strip 19 is connected to the outer side surface of the sector-shaped filter plate 8, and a groove is provided on the inner side surface of the output pipe 2. The convex strip 19 slides along the groove. A fixed disk 9 is fixedly connected to the second V-shaped plate 13, and a limiting groove 18 is provided on the side surface of the fixed disk 9. The sector-shaped filter plate 8 is slidably connected with the limiting groove 18. In this way, the sector-shaped filter plate 8 can stably rotate around the fixed disk 9. The central axes of the input pipe 1, the output pipe 2, the rotating ring 3 and the fixed disk 9 are collinear. The central axis of the arc-shaped groove 34 is collinear with the central axis of the rotating ring 3. In this way, the sector plate 21 can rotate around the central axis 16.

[0029] In an embodiment of the present invention, the first V-shaped cavity and the second V-shaped cavity are respectively located in the upper half parts of the input pipe 1 and the output pipe 2. Dust removal doors 10 and plate replacement doors 11 are respectively installed on the top surfaces of the input pipe 1 and the output pipe 2. By opening the dust removal door 10, the scraped fluff impurities can be cleaned. By opening the plate replacement door 11, a new sector-shaped filter plate 8 is placed at the notch, and the sector-shaped filter plate 8 is pushed to push the new sector-shaped filter plate 8 out of the second V-shaped cavity. The oldest sector-shaped filter plate 8 on the edge will enter the second V-shaped cavity, and the old one is taken away and replaced. In this way, the replacement of the old sector-shaped filter plate 8 can be realized while ensuring the normal operation of the device, and the replacement process is simple.

[0030] In an embodiment of the present invention, the rotation-to-reciprocating linear component includes a rotating column 22, a turntable 29 and a first movable rod 30. The rotating column 22 is coaxially and fixedly connected with the turntable 29. The rotating column 22 is rotatably installed on the second V-shaped plate 13. One end of the rotating column 22 is connected with a driven bevel gear 24. A driving bevel gear 23 is connected to the central axis 16. The driving bevel gear 23 is meshed with the driven bevel gear 24. The rotation speed of the driven bevel gear 24 is greater than that of the driving bevel gear 23. Preferably, when the driving bevel gear 23 rotates one circle, the driven bevel gear 24 rotates more than 8 circles. One end of the first movable rod 30 is hinged to the edge of the turntable 29. The other end of the first movable rod 30 is hinged to a second movable rod 31. A limiting plate 32 is connected to the second V-shaped plate 13. The second movable rod 31 passes through a limiting hole on the limiting plate 32. The second movable rod 31 is connected to the reciprocating seat 20. The second movable rod 31 can only perform linear motion under the action of the limiting hole.

[0031] In an embodiment of the present invention, a fan blade 26 is installed in the second V-shaped cavity. The rotating shaft of the fan blade 26 is fixedly connected coaxially with a third gear 25. A second gear 17 is fixedly connected to the central shaft 16. The second gear 17 is meshed with the third gear 25. The rotational speed of the second gear 17 is less than that of the third gear 25. Preferably, the rotational speed of the third gear 25 is more than 50 times that of the second gear 17. A fixed seat 27 is connected to the second V-shaped plate 13. A fixed shaft 28 is connected to the fixed seat 27. The fixed shaft 28 is rotationally connected to the third gear 25 to support the third gear 25.

[0032] The working process of the embodiment of the present invention is as follows: When in use, the motor 6 and the blower are started to purify the fluff impurities in the air. The filter net 15 will rotate, and then the blade 14 will scrape off the fluff impurities on the surface of the filter net 15. The scraped fluff impurities will fall into the first V-shaped cavity. At the same time, the reciprocating seat 20 will perform a reciprocating linear motion, so that the telescopic hole cleaning rod 36 is inserted into the mesh holes of the filter net 15 to clean the mesh holes. It is easy to understand that there will be some telescopic hole cleaning rods 36 that do not align with the mesh holes, and these telescopic hole cleaning rods 36 will contract; in addition, the telescopic hole cleaning rods 36 inserted into the mesh holes will rotate along with the filter net 15, and then drive the sector plate 21 to rotate. The sliding seat 35 moves along the arc-shaped groove 34. Before the sector plate 21 touches the second V-shaped plate 13, the reciprocating seat 20 will move backward, so that the telescopic hole cleaning rod 36 is separated from the mesh holes of the filter net 15, and under the action of the return spring, the sector plate 21 returns to its original position.
